Lolium perenne, common name perennial ryegrass, [1] English ryegrass, winter ryegrass, or ray grass, is a grass from the family Poaceae. It is native to Europe, Asia and northern Africa, but is widely cultivated and naturalised around the world.
The primary species found worldwide and used both for lawns and as a forage crop is perennial ryegrass (Lolium perenne). Like many cool-season grasses of the Poaceae, it harbors a symbiotic fungal endophyte , either Epichloë or its close relative Neotyphodium , both of which are members of the fungal family Clavicipitaceae .
Lolium multiflorum (Italian rye-grass, [2] annual ryegrass) is a ryegrass native to temperate Europe, though its precise native range is unknown. [3] It is a herbaceous annual, biennial, or perennial grass that is grown for silage, and as a cover crop. [4] [5] It is also grown as an ornamental grass.
The flowers are usually hermaphroditic—maize being an important exception—and mainly anemophilous or wind-pollinated, although insects occasionally play a role. [10] The perianth is reduced to two scales, called lodicules , [ 8 ] : 11 that expand and contract to spread the lemma and palea; these are generally interpreted to be modified sepals.
Perennial ryegrass staggers is poisoning by peramine, lolitrem B, and other toxins that are contained in perennial ryegrass (Lolium perenne), and produced by the endophyte fungus Epichloë festucae which can be present in all parts of the grass plant, but tends to be concentrated in the lower part of the leaf sheaths, the flower stalks and seeds.
The name Kentucky bluegrass derives from its flower heads, which are blue when the plant is allowed to grow to its natural height of 60 to 90 cm (2 to 3 feet). [9] Poa pratensis is the type species of the grass family Poaceae. Five subspecies are accepted. [10] Poa pratensis subsp. dolichophylla (Hack.) Portal – Corsica

Some plants have bracts that subtend the inflorescence, where the flowers are on branched stalks; the bracts are not connected to the stalks holding the flowers, but are adnate or attached to the main stem (Adnate describes the fusing together of different unrelated parts. When the parts fused together are the same, they are connately joined.)
